摘要
经真空-堆载联合预压处理的围垦海岸滩地产生的沉降变形给工程生产带来诸多问题,通过对比分析,采用有限元法和实测资料预测法计算最终沉降,证明有限元计算地基沉降是可靠的;进而采用有限元预测工后沉降稳定时间,根据预测结果解决实际工程中出现的问题。
The settlement deformation of the reclamation tideland, strengthened by vacuum combined with surcharge preloading, has great influence on the engineering production. The final settlement of foundation calculated with prediction method and finite element method were compared, and the latter was found more reliable. Thus, the finite element method was taken to predict the post-construction settlement and the settlement stability time. The prediction results could be used to solve the practical engineering problems.
